In 1942, Hollywood actress Hedy Lamarr, in collaboration with composer George Antheil, co-invented frequency-hopping spread spectrum technology. Designed to prevent the jamming of radio-controlled torpedoes, this innovation ensured secure and interference-resistant communication. Initially overlooked, Lamarr's invention laid the groundwork for modern wireless technologies like Wi-Fi and Bluetooth, significantly influencing the development of reliable communication networks and devices used today.
